Hello there,
i know that this topic has been already debated several times but I couldn't find any solution to it.
I'm running MIUI 1.8.19, android version 2.3.5, kernel version 2.6.35.7-g3cc95e3, baseband I9023XXKB3.
Wifi signal is extremely weak, few meters away from any router and the connection becomes extremely unstable making the wifi experience a total nightmare.
I've been previously tried NSCollab and also different baseband configuration files but nothing seems to get things better.
For what is worth (even though the wifi is bad anywhere and with any router) my router is a Linksys WRT150N running on DD-WRT.
The Nexus S wifi thing seems to be a little bit controversial. Some users seem having no problem with it, some other experience the same problems i do.
Question #1: is that a hardware, software or both kind of problem?
question #2 : is there any workaround that would allow me at least to comfortably browse the internet from my bedroom (5-6 mts away from my router) without getting disconnected every other 30 sec?
Thank you in advance,
D.
You kept a phone that can't hold a wifi connection over a distance of 5m? I'd have returned it on day 1.
It's normal that the distance of WIFI on smartphones is less than say a laptop or pc, but 5m is definitly not normal.
Verify w/ other wifi networks, same problem = return it. If not, bad luck, might be the combination of your phone + the router not working properly.
You can try changing radios to see of that improves your situation, for some it did.
Yes, it is normal having a weaker wi-fi but my blackberry has no problem at all. it is the nexus and it seems to be quite a widespread problem around the globe.
Well i was abroad on business and couldnt return it. Just looking for clues....
I know that netarchy's kernel uses updated wifi drivers, you can try flashing that and see if it does anything.

Hi there,
i tried several kernels: netarchy, matrix and also installed MIUI and also tried the MIUI Brainmaster ROM. Same result: in my bedroom the wifi signal score a miserable -85/90 db. Is there any kernel out there optimized for wifi? I mean, it seems that the wifi weakness on the nexus S is a common problem.
Thank you in advance.
It sounds as though you have a hardware problem or a router problem. I have to go to a room in the other side of my house to get -90 db and even then it doesn't disconnect. I have to get about 200 feet away before it disconnects.

Also it might have something to do with interference on whatever channel you are connecting on but I don't really know enough about wireless networking to help you troubleshoot that.

What i'm wondering is wheter Samsung uses different wifi chipset on the same phone cause i'm not the only one complaining about it. just google "nexus s weak wifi" and you'll see hundreds of people with the same problem.
still wondering if there's a software solution to it.

It has been documented that the Nexus S uses an under powered wifi chip. The chip uses less power but with that comes a weaker signal.
mine seems to be weaker than average...
Yours does seem weaker than normal, but no nexus s has decent wifi range.
What I have done is purchase 2 old linksys wrt54gl routers, have them both loaded up with DD-WRT and then link them (bridged mode or WDS if you prefer) and situate the routers in either end of my house. I have a decent sized 3 bed detached house, with a 70ft garden, I can now get a reliable wifi connection near the end of my garden on my nexus, where as previously I couldnt get to the back door
Might be an old thread, but I just traded my trusty HD2 for a Nexus S and god I hate the WIFI reception on this thing.
I am on stock 2.3.4 Rooted with KD1 radio and 2.6.35.14(Pete's) kernel. Tried just about anything out there, and nothing worked out.
Being a Pure Google experience phone, I was expecting a lot more happening for this phone, but it seems that my 2009 released HD2 was way better for all it had to offer.
Subscribing to this thread!
WIFI is fine for me, same as with HTC Desire, and stronger than iPhone 3G...
Its terrible on my Sprint Nexus.
Where I have an Ipod touch and a LG Optimus, they get an 'excellent' connection anywhere in the house. The Nexus drops the connection all the time, shows a 'poor' 5Mbps connection.
Will swapping the phone do any good?
OK.
I bought my Nexus S yesterday and I was soooo disappointed because of its poor wifi reception... But...
I am a network Administrator and a few minutes ago i just couldn't beleive that about 10 meters away from our Cisco Antennas i had about 89db signal so i started playing... and guess what i now have 55dbs at the same spot! What i found out is that Nexus S doesn't work well with High Frequencies so I disabled channels 8-13 and my AP had to work on the low channels and BAM! everything works fine now (My phone is in stock FW)
I hope I helped

Awesome tip! Thank you so much
I found this channel number which it uses to make no difference to the wifi performance.
I tried channels 1,6,11, no difference.
The phone just has poor wifi.
As a note, usually I don't use the low channel '1', as this gets interference from microwaves more than the upper channels.
just bought a Nexus and and experiencing heavy wifi issues.
I tried changing AP channel but doesn't fix.
Testing signal strenght with a LG Optimus one for comparison:
1- LG: -72db. stable
2- Nexus S: -85db web pages loading fails quite often.
Tomorrow my NS will return to the store. Bye Bye

Well, I capped out my Tmobile data at 5gb so now I'm going to try and start using my wifi more on my phone.
I was in a coffee shop that my laptop easily latches on to the wifi signal. However, my Nexus S wouldn't latch on to the wifi because the signal was to far away. The router was only about 20 feet away...and again, my laptop had no problems with it.
Is there some kind of software bug that makes the Nexus S wifi to weak? Can this be improved?
I've noticed weaker performance at my home compared to previous devices. It could be down to the hardware (ie antenna) but you could possibly try boosting the power given to the Wifi chip? Like when you install DDWRT on a router you can boost the output power, maybe something similar applies here.
I have a copy of the Android source on my laptop so I will dig around and see if there is anything. Can't guarantee it though, I'm also quite busy.

Hi all,
Wonder if any of you have bad reception with WiFi? I have an extended range router that allows me to get full bars on wifi even at the far reaches of my yard (about 300 feet) when i had the Atrix and the Inspire. Now with the infuse, as soon as I leave the indoors and step outside my signal bars drop to 2 or 3 and gets worse very quickly as I walk away from the house. Is this a bad radio, bad phone or am I just asking to much?
Thanks
The radio is kind of craptastic

Yes its weak. I'm only 5 feet away from my wireless n router and it flucuates between 4 and 5. sometimes it feels like touching the sides of the phone degrade the signal. I'm on my 3rd infuse and it has the same issue but this one seems to having better reception. again im only 5 feet from my router and non of my other wifi devices haves less then 5 bars. also testing the infuse at att vs other phones the infuse always had less bars for wifi.
Hopefully a radio update will help with this in the future. It's virtually the same hardware that's in many phones. The antenna array shape or location may have something to do with it, though. I'm guessing it's in the "chin" somewhere.
EDIT:
What a coincidence! I just got the update pushed to my phone from AT&T, and the new baseband FIXED my poor wifi reception.
Thanks AT&T / Samsung / Engineers!

I have two Infuse 4G units with same wifi problem. no wifi signal where I can watch youtube with blackberry curve and iphone 3 . talked to ATT tech support. no newer version of baseband. talked to samsung tech support and tried soft reset and hard reset. no improvements. should I just return them or try to fix the problem?
I get a wifi signal in all 3 stories of my house.
Get wifi analyzer from the market and see what channel is strongest for your router/phone. Switch the router to that channel (it'll probably have the least amount of competing signals), and reconnect.

& bars usually dont mean much i usually have 65mbps connection no matter what the bars say
My wifie provides good reception. Sometimes I lose connection to my wifie even though she is sending strong signals...but usually after dinner out, maybe some flowers, I can reconnect.
I have no problems with my wifie.

Thats funny
Mine is pretty shotty as well. Granted, even if I have 1 "bar" my speed is fine, I can't get a signal about 40 feet outside my house (about 100 feet total from my router).. My Inspire couldn't get signal there, either, but even being side by side with my wifes iphone 4 she gets 3 bars of signal from that same spot. Maybe it's an Android issue? It's not a big deal, as I'm in a "4G" area and speeds are good enough, but I just thought i'd share that I have the same issue.
Still the best phone i've ever owned, as a whole.
Did you try what I recommended in This post?

How do you change the channels on your router?

If you tell me the model of your router I can give you specific details, but the short version is that you go into the setup page for your router (where you set your security settings and all that), and probably under the wireless page you should see settings for channel, country, etc. For my old netgear router the default was 6 I believe.
Before I changed channels, I used the wifi analysis tool and saw that there were 4 other wireless networks on that same channel. Changing to another channel helped quite a bit.
Mine is really crappy too. I would say pathetic and non usable most of the time.
I go to the local airport and to any restaurant that has free wifi and my blackberry get a full signal while this Infuse does not see anything. At home is only goes about 35 feet away from the router. Me telling hotspots to change their channel is noit a viable option. I wish I knew this before buying this phone.
I see this post (see below) and wonder if there is a ROM with this fix already in it. I am running CatyRom but I have tried all the other roms like CYM, Miui and so forth and the poor signal is the same.

not an android issue, its phone specific but there may be many phones with the same shortcomming. wifi reception was way better on the captivate (I wish I still had that thing). but the infuse doesn't cause me any problems.
switching channels at home can't hurt. most routers are on channel 6 by default so it probably has many competing signals. not too much you can do if you are out and about though.
Anyone else have an issue with a weak wifi signal? i have to be in the same room for it to connect. I can be anywhere in the house with my laptop and tabet.
Same for mine. My Infuse is about a week old to me and is unrooted and stock. The WiFi is very week and won't connect 30 feet away from the router. All of my other phones show weakness, but they will connect.

I have a linksys
mine does it too. i could be right next to my iPhone that is connected to the same thing and it'll have full coverage but the infuse has nothing.
I got the phone last week and notice the same thing. I also noticed it has the iPhone deathgrip issue on wifi. I can cover the back up with my hand and watch it drop a bar on wifi. Give it some breathing room and bar comes back. My biggest gripe is it sometimes doesn't want to get back on wifi if you get out of range.
Ni WiFi issue here, I have Buffalo and DLink routers, I get strong and consistent signal with both. I have my router in 2.4Ghz 802.11N (no GN or BGN)
Ugh thank gawd I haven't noticed those issues yet, other then last week it wouldn't connect at all was just stuck on obtaining connection so I just rebooted the phone and it connected fine, from outside in the middle of the street to test it.
The wifi on the Atrix though is a beast because when I went to Chumash Casino and Resort we had to rely on wifi (it's in the hills and no network at all) and the Atrix connected 8/10 tries vs my Infuse 3/10 to the casino sh*tty free wifi... And the Atrix picked up other Wifi spots (adhoc) etc... sigh only thing that blows about the Infuse!
Yup my infuse hates wifi, wish it wasn't true but it is
.......infuse.....Infused....infusion.........
Another user posted this link. I think it could possibly explain some of the issues I've been having. I have issues at work especially where we have multiple access points. If I forget the network and reconnect it links right up. The good news is I don't really see a reduction or improvement in browsing with a dot or full bar. At least not the feel, I haven't measured with a tool.

Bugs in the software and firmware, what could go wrong?
i noticed a big drop in wi-fi strength after changing my rom from stock to infused 2.1
Overall I am loving this phone. I have never had an Android phone this fast. I can't find a hint of lag on this thing.
I am, sadly, having a couple of other issues and want to get other peoples thoughts on things before I do anything "Drastic".
1) I heard somewhere they boosted the sound by 25%? If I have mine at full... I am hearing static and popping... like it is too much for the speakers. This is when I get a text/ringtone, or when I am playing a game (Robot Unicorn Attack for instance... don't judge).
2) Wifi.... I am getting weird "lag" when I am on wifi. Websites take longer to connect to and load... same with apps and the Playstore. Speed test I am only able to pull down 15MB/s. Low ping... but it takes forever (6-10 seconds) to connect to start the test. Have tried three different routers, same results (Netgear,an E3200, and a D-Link). Everything looks normal under settings. Full strength (in the room of the router... gets worse when I am downstairs). I unchecked the Wifi Optimization. Also it is doing this on 5 and 2.4 GHz.
3) GPS Lag - It seems to be taking longer than normal. I am going on a trip this weekend, and I will really get to test this then... but wanted to know if this is normal for an HTC device now a days (last one I owned was the Thunderbolt.... shivers, and GPS was always wonky).
Any help appreciated. Thanks!
1 - In my experience so far, the speakers are definitely louder, but I haven't found any distortion besides audio files that I artificially increased the volume on for previous devices.
2 - I haven't seen any WiFi lag yet. But I'm on vacation currently and the internet here is only 12mbps, instead of my 65mbps at home.
3 - The Engadget review noted some wonky GPS issues.

If you could... when loading up a web page or something... see if it is taking longer than normal to connect to a web page initially. Mine is acting like there is no internet... then all the sudden it loads up fine.
I am also noticing MMS is taking longer than normal to send (I had an S4 before this and it didnt take half as long... maybe it was compressing it more?)
I have just had radio issues in the past with HTC devices and want to nip them before it is too late.

Sadly I am still having this issue. Now that the phone has been out a week, anyone noticed anything?
I am not having issues connecting to the Wifi, I am just having issues connecting to the internet once connected to the Wifi. I have now tried this on 5 different home routers and several public Wifi areas and all the same results: going to a webpage has a delay anywhere up to 15 seconds before the page starts to load, and apps have issues connecting as well (Instagram will tell me unable to refresh, and Facebook will tell me I have no network connection). I have tried everything: Renamed the Device to HTC One, tried switching to 2.4 and 5 Ghz band, Unchecked WiFi Optimization... nothing is fixing this "lag".
Speaker issues - Still hearing a popping and crackling of the speakers, and I am seeing others are having the issue as well.
GPS - Went on my trip, I think I was getting the typical "Chicago GPS" lag before, as I would normally get a lock on with my GPS in 3 seconds or less while out in the middle of no where this past weekend.
I personally do not want to go through 15 phones trying to find one that has working WiFi, as it seems the One series has been having issues with WiFi since 4.3. Anyone have any suggestions?
Just browsing the forums for a WiFi issue my M8 has, to hopefully find a fix. This is what I have, not sure if it fits your symptoms as well:
Speedtest on network and bluetooth 11.39Mbps down / 3.85Mbps up
on network no bluetooth 13.98Mbps down / 3.98Mbps up
Speedtest on WiFi and bluetooth 2.53Mbps down / 5.53Mbps up
on WiFi no bluetooth 20.79Mbps down / 6.67Mbps up
Basically, if I keep my BT off, my speeds are fine and inline with what I expect to get, but if it's on it's at a crawl. Seems like WiFi and BT don't want to work in tandem. I haven't found much information on my issue yet, but I'm hoping to before I either do a a full reset or warranty replacement.

Hey gang,
Any Note 5 owners experiencing any wifi connectivity issues? I've found that the connection becomes completely unresponsive if I lose a single bar of wireless signal, and even during regular usage with full signal, the wifi connection will just drop off and reconnect back to the access point. I took a Galaxy Note 2, a Nexus 6, and the Note 5 to one of the spots where 1 bar drops, the Note 2 and Nexus 6 have no issues and still get 120Mbit on Speedtest. The Note 5 just times out until I get the signal back up to full strength.
I've made sure Smart Network Switch is disabled, and I don't see anything to disable any Wifi optimizations so I'm guessing that isn't an option anymore.
Regards,
--Henry
I haven't had any issues with my note 5 so far... have you tried rebooting the router? Every week or two I have to do that with my router cuz of weird stuff like that.

Unfortunately a router reboot does nothing, and I had a feeling it would do nothing since all the other devices are on wireless perfectly fine. Only the Note 5 has issues.
The router isn't a slouch either, it's an Asus RT-N66U so it's not some kind of cheapy wireless router

Sent from my SM-N920T
You would think that with Samsung being the reputable company they are, they would ensure their devices weren't plagued by these issues.
I'm on the fence about returning the note 5, the wifi drops out so much that I'm not going to settle with paying a big chunk of change just to have a faulty device.
Haven't seen any WiFi drops here. I rely on WiFi Calling while at the office and it held stable both Friday and today. Browsing seemed fine too.
I'm having the same issue. The connection doesn't drop, just becomes unresponsive. I have to toggle it to get it back.
Unfortunately, just because they're the same model does not mean the exact same parts were used to make them.
It may be that some phones were built with a router from a bad batch/supplier, while other sm920t are without the fault.
It may be worth a shot to do a warranty replacement. You can do it as many times as you need to get a properly working device, even. I dont think theres a charge, and if it is it's negligible. If you're the type to think you shouldnt have to pay for their mistake (like me...) you could probably convince customer service to credit the fee. Just remember to be nice... customer service is a crappy job, so you'd be surprised how far they'll go to help the people whom brighten up their day :-]

Oh it's not that it's not fast -- it's extremely fast! The problem is that the wifi constantly drops, even in the same room as the router, the wifi drops connection and then reconnects, interrupting anything that I was currently doing.
Hmmm, that's no good. I haven't had that issue with the note 5. if I did have that issue, I would try to turn airplane mode on, shut down the phone and boot to stock recovery, wipe cache, reboot, turn wifi on and see if that helps - not saying it will, but if it isn't working right to begin with, it isn't going to make it any worse.
Just a thought...
Additionally, I have had that problem periodically ( not with the note 5 cut its only a few days old), though it usually affects multiple devices, not just one device at my house. When it happens, even rebooting the router and modem doesn't always help. There have been a few times that I have called my cable provider and they "re provisioned" the modem while I was on the phone with them. After that, the problem seemed to go away for many months. The issue was actually the cable modem, not my router.
I posted in the generic Note 5 thread on wifi issues. Im having the similar problems maintaining a stable connection on both work and home networks. Home 5ghz N wpa2 psk, work 5ghz N eap-fast/peap, and work hotspot 2.4ghz open. All networks exibit the same behavior, the note has trouble initially connecting, where it try and drops several times. A bit later it will show the popup that it connected to network name. Any queries seem to be extremely slow or time out. I have manually set my DNS servers to googles with no change in behavior. Wireless calling effectively doesn't work while this is going on. Im going to get a replacement phone tomorrow, but this seems more like a software or driver issue. My nexus 6 had no issues connecting to these networks. My note 4 did exibit connection stability problems on my home network, even though the AP is barely 15 feet away. Im heading to my Aptment in texas this weekend, I have ubiquti AC wireless APs set up there, will see if AC connectivity is at least solid.
Asus routers tend to not play nicely with Samsung devices unfortunately, I have an asus router as well and I have had multiple samsung devices that are unable to maintain a stable connection as well. Something that I have done to make it less annoying is turn off wifi power saving mode. If you don't know how open your dialer and dial *#0011# then go to wifi at the top right. Usually helps the issue. Also I only have my samsung devices connect to my 2.4ghz network instead of the 5ghz.
